When her father dies and she is left in the care of her conniving brother Laban, Rebekah knows her life has changed forever. Her hope for the future is restored when she falls in love with her cousin Isaac, and their relationship starts strong. But marital bliss cannot last forever, and the birth of their twin sons marks the beginning of years of misunderstanding, disagreement, and betrayal. The rift between them grows wider and wider until it is surely too deep to be mended. And yet, with God all things are possible.

Sarai, the last child of her aged father, is beautiful, spoiled, and used to getting her own way. Even as a young girl, she is aware of the way men look at her, including her half brother Abram. When Abram finally requests Sarai's hand, she asks one thing--that he promise never to take another wife as long as she lives. Even her father thinks the demand is restrictive and agrees to the union only if Sarai makes a promise in return--to give Abram a son and heir. Certain she can easily do that, Sarai agrees.

But as the years stretch on and Sarai's womb remains empty, she becomes desperate to fulfill her end of the bargain--lest Abram decide that he will not fulfill his. To what lengths will Sarai go in her quest to bear a son? And how long will Abram's patience last?
